ACETYLENE- GAS GENERATOR.

` Speccation of Letters Patent.

Patented Apr. 1, 1919.

Application led November 26, 1915. Serial No. 63,430.

To all whom t may concern:

Be it known that I, JAMEs A. MUSE, a citizen of the United States, residing at Cleburne, in the county of Johnson and State of Texas, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

My invention has relation to an improvement in acetylene gas generators and in such connection it relates more particularly to the arrangement and construction of valve controlling the discharge from the carbid chamber or hopper together with the arrangement of the gas bell which automatically operates said valve.

' In the carrying out of my invention the usual carbid chamber or hopper is traversed by the stem of the valve controlling the outlet from the hopper; the valve itself is coneshaped with spreading sides and is pressed upward by a spring interposed between (and protected by) the under hollow face of the valve and a support or strap extending from the base of the hopper below the valve. In. conjunction with this valve arrangement, a gas bell is arranged to inclose the hopper and in descending to rest on and depress the stem of the valve which, traversing said hopper, projects above the hopper.

The nature and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof in which,

Figure l, is a vertical sectional view of an acetylene gas generator provided with a' valve mechanism embodying the main features of my invention, and

Fig. 2 is a cross sectional view on line 2 2 of Fig. 1.

Referring to the drawings, 1 represents the water chamber of the generator and 2 the neck having a water seal 8 wherein the gas bell 4 is adapted to be supported. Within the neck 2, and properly supported therein in any suitable manner, is arranged the carbid chamber or hopper 5. The hopper 5 has the usual conical discharge end or base (3v having a central opening forming a valve seat and a discharge `trom the hopper to the water chamber 1.

The hopper 5 is traversed by a valve stem 7 carrying near its lower end the hollow conical valve 8, the apex of which enters the valve seat in the discharge end 6 of the hopper 5. This valve 8 'is normally forced upward into the valve seat by preferably a spring 9 interposed between the hollow under side of valve 8 and a strap 10 depending from the base of hopper 5 and also traversed by the lower portion of the valve stem 7. The spring 9 is preferably coiled about the stem 7 and enters at the base, the troughlike horizontal portion 11 of the strap 10. The spring is thus protected from carbid issuing from hopper 5 by irst the conical valve 8 whose walls form a shed to protect the spring and second by the trough 11 of strap 10 which protects the lower end of said spring.

The valve stem 7 in traversing the hopper 5 projects some distance above the up- 4per end of said hopper which end is closed y lid 12. The valve stem passes through the lid, and its upper end is provided with an adjustable nut 13. This nut 13 serves as a means for limiting the movement of the valve stem 7 downward through the hopper 5.

When now the gas in the neck 2 becomes exhausted, the upper end of said neck being closed by the gas bell 4, said bell 4 will descend in its water seal 3 until it rests on nut 13 of valve stem 7. The valve stem is then depressed against tension of spring 9 and the valve 8 is opened to permit more carbid to enter water chamber 1. When suticient quantity of gas has been generated to elevate gas bell 4:, the stem 7 and valve 8 are pushed upward by the spring 9 to close the hopper outlet.

Having thus described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is,-

In an acetylene gas generator, a carbid hopper, a conical valve closing the lower outlet end of said hopper, a strap at the upper end of the hopper, a strap carried by the hopper below the outlet, a stem for the valve extending above and below said valve and traversing both straps and a spring coiled about that portion of the stem extending below said valve and interposed between the under face of the valve and the lower strap, in combination with a gas bell and water sealing chamber inolosing the carbid ohainname to this specification in the presence of ber, said gas bell arranged to lmplnge upon two subscribing Witnesses.

Jche upper end of the Valve stem and de ress l the Valve stem against the tension ofpsaid JAMES A MUSE' 5 spring to open the valve when said Toell de- Witnesses;

soends in the Water sealing chamber. M. N. BAULDWIN, In testimony whereof I have signed my S. A. DoUGLAss.
